爲什麼我無法運行這個Erlang演示應用程序？

我有一個類似的問題，因爲here for running an rebar app 爲什麼我無法運行這個Erlang演示應用程序？

基本上，我想從運行演示代碼：https://github.com/hukl/fancyapi

當我在根目錄下，而我做的：

 
→ erl [...] -pa ebin -pa deps/*/ebin 
Erlang R15B02 (erts-5.9.2) [source] [64-bit] [smp:8:8] [async-threads:0] [hipe] [kernel-poll:false] [dtrace] 

Eshell V5.9.2 (abort with ^G) 
1> application 
1> . 
application 
2> application:start(fancyapi). 
{error,{"no such file or directory","fancyapi.app"}} 
3> application:start("fancyapi"). 
{error,{bad_application,"fancyapi"}} 
4>

如何ERL是否會找到fancyapi代碼？

適合我。你運行過'rebar compile'嗎？它是否在'ebin'目錄下產生了'fancyapi.app'文件？ – legoscia 2013-02-21 15:10:38

是的，那是我的問題。 – poseid 2013-02-21 15:34:05

好吧，太好了......我沒有意識到需要運行「鋼筋編譯」 – poseid 2013-02-21 15:33:48
